An improved procedure for the generation of high-avidity anti-human B blood group monoclonal antibodies (MAbs) was developed. One of them, termed 7A1-2, showed excellent qualities of titer, avidity, and intensity required for use as human B blood typing reagent. Hemagglutination inhibition studies with monosaccharides and oligosaccharides were carried out to determine the specificity of the MAb 7A1-2. These studies indicate that the antibody reacts with the immunodominant region of the antigen which is known to confer the serologic specificity of this blood group.
